问题如下：
Backtesting of actual losses to VaR calculations is required according to the Basel Committee. How many exceptions occur in a 250-day trading period would result in increasing the capital multiplier from three to four?
选项：
A.zero to four
B.four to seven
C.seven to nine
D.ten to more
解释：
D is correct.
考点：Backtesting VaR
解析：
If there is ten or more backtesting violations, capital multiplier need to be increased from three to four.
capital multiplier是不是就是那个k。k从3增加到4，增加了1，所以number of exceptions对应就是10+？
看了看历史提问，这个问题还属于考试范围吗。
